A weebo is the entire adventure including, but not limited to, the actual process of smoking. So when going hiking and smoking along the way, the entire hike is regarded as a weebo, not just the part when you were smoking.

There are no real requirements for the adventure as long as you and your friends consider it one. So a weebo could be anything from smoking in a new spot to a month long cross-country trip with a quarter pound.

"We went on a weebo at the state park today."
"We're looking for some good weed for our trip up north so we can make it a weebo."

A weebo is much like an Otaku. Weebo's-or commonly misspelled, Weaboo- is an over obsessive fan of Japanese culture, and are giving Otakus a bad name. They revolve their whole lives around anime and manga, usually with the main stream material. The common Otaku likes anime, and does occasionally cosplay. Weebos just cosplay and watch anime to be like the Otakus. Weebos are usually friends with Otakus, and want to impress them. (So they watch Naruto, Inuyasha, etc.)

Most weebos speak Waponese, or use google translate to act like they know Japanese.
They misuse the words "Baka," "Kawaii desu,""Moshi-Moshi," "Aishiteru," and so much more.
Most of them use names on chatrooms with the word "Anime," "Kitty," "Maid," and "Manga" beware!
The otakus would like them out of their fanbase, please.
